KSD9700 termosztát hővédő kapcsoló

KSD9700 sorozatú hőmérséklet-szabályozó kapcsoló (Hi-Amp levágás & akkumulátor hővédő termosztát) nagy érzékenységű bimetál lemezből áll, mozgó érintkező, statikus érintkezés, fix alap, héj, hőálló vezeték, stb. Munka közben, a bimetál korong szabad állapotban van, a mozgó érintkező és a statikus érintkező zárva van, és az áramkör be van kapcsolva. When the temperature of the electrical appliance rises to the operating temperature of the thermal protector due to a fault, the bimetallic strip generates internal stress due to the heat and quickly acts, pushing the moving contact away from the static contact to disconnect the circuit. Thus, the power supply of the faulty electrical appliance is cut off to protect the electrical appliance. When the temperature of the protected electrical appliance drops to the rated reset temperature value of the thermal protector, the bimetallic strip returns to the initial state, the contact is closed, and the electrical appliance resumes normal operation. This product has the advantages of low resistance, fast temperature sensing, fast action, safety and reliability, and small size.

Hi-Amp Hi-Temp KSD9700 Bimetal Disc Temperature Switch N/O Thermal Protector

The current overload protection principle of KSD9700:
The current passes through the moving contact terminal (bimetallic strip), and then the static contact terminal is connected to the electrical appliance (such as a battery, stb.) to form a circuit. When the current of the electrical appliance is too large and exceeds the trip value set by the protector, the protector will cut off the power supply within the set time to protect the electrical appliance.

The temperature protection principle of KSD9700:
The current passes through the moving contact terminal (bimetallic strip), and then the static contact terminal is connected to the electrical appliance (such as a battery, stb.) to form a circuit. When the electrical appliance does not work properly and the surrounding temperature is too high, the heat is transferred to the bimetallic strip to reach the corrected trip temperature, causing the electrical contact to quickly disconnect and cut off the circuit. Amikor a hőmérséklet a visszaállított hőmérsékletre csökken, the bimetallic strip resets and quickly closes the electrical contact to connect the circuit, and continues the cycle.

KSD9700 structure and application
The KSD9700 series products are a kind of thermostat with bimetal as temperature sensing element. Amikor a készülék megfelelően működik, the bimetallic strip is in a free state and the contact is in a closed/open state. Amikor a hőmérséklet a működési hőmérséklet értékére emelkedik, the bimetallic element generates internal stress due to heat and quickly moves, opens/closes the contact, cuts off/connects the circuit, and thus plays a role in thermal protection. Amikor a hőmérséklet a visszaállított hőmérsékletre csökken, the contact automatically closes/opens and resumes normal working state. It is widely used in household electrical motors and electrical equipment, such as washing machine motors, air conditioner fan motors, transzformátorok, ballasztok, elektromos fűtőberendezések, stb.

KSD9700 series temperature control switch precautions
⑴ When using contact temperature sensing installation, the product should be close to the installation surface of the controlled device.
⑵ Do not collapse or deform the plastic or metal shell during installation to avoid affecting the performance.
⑶ The metal shell KSD9700 has an insulating jacket. Do not remove or crush the additional insulating jacket during installation to avoid leakage and ensure safe use.
⑷ KSD9700 is used in circuits with a current of no more than 5A~45A, and a copper core wire with a cross-section of 0.4-0.75㎜2 should be selected to connect it.
⑸ The product should be stored in a ventilated, tiszta, dry place with no corrosive gas and a relative humidity of less than 90% and an ambient temperature below 40°C.
